Original finish on WW1 Propellers

[Smithmaps]

Could anybody advise?

I have an original WW1 propeller from a Sopwith Dolphin, which is in need of re finishing.

The boss is finished in some form of shelac, and it would appear to have been canvas covered on the blades that has long since gone, and now presents a very rough finish.

Obviously I would not entertain any form of varnish, but was wondering if anybody could advise on what would have been used originally, so that I can return it to its former glory.

I also have the top and front cowlings in aluminium, so all I need is a few more sticks and canvas!

Many thanks
